To study the association between maternal drug use in early pregnancy and orofacial cleft in the infant.


Register analysis based on prospectively collected information.


All delivered women in Sweden July 1, 1995, through December 31, 2001.


Presence of orofacial cleft in infant.


Prospective information on maternal drug use during the first trimester, as reported in early pregnancy, was studied in 1142 infants with orofacial clefts, isolated or with other malformations, excluding chromosome anomalies. Any drug use was not associated with clefts (odds ratio [OR] = 0.98, 95% confidence interval [95% CI] = 0.85 to 1.13), with isolated clefts (OR = 0.92) with isolated median cleft palate (OR = 1.03, 95% CI = 0.79 to 1.36) or with isolated cleft lip with or without cleft palate (OR = 0.86, 95% CI = 0.71 to 1.05). Reported use of multivitamins, folic acid, or B(12) was not associated with a decrease in orofacial cleft risk (OR = 1.00, 95% CI = 0.63 to 1.52). ORs above 2 were seen for some drugs: sulfasalazine, naproxen, and anticonvulsants, but only a few exposed cases occurred. An association between glucocorticoid use and infant cleft was indicated and seemed to be strongest for median cleft palate.


Maternal drug use seems to play only a small role for the origin of orofacial clefts, at least in Sweden.
